4 times mode – When selected indicates that machine is on 4 times torch mode. Under extensive welding
seams, the operator can press and release torch trigger; the machine continues to welding. Press and release
button to stop welding.
MIG/MAG spot timed welding mode - When selected indicates that the machine is in MIG/MAG spot welding
mode.
Set the spot time by pressing the right knob (9 - Fig.5) until the SPOT TIME LED lights up in the welding cycle
and turn the same knob for the desired time. Start spot welding by pressing the torch trigger and continue
pressing until the end of the set MIG welding program.

U Adjust the welding voltage by pressing the right knob 9 (Fig. 5) until
2
LED 1 - Fig. 6 lights up and turn the same knob.
Adjust the wire motor speed between 0.5 - 30 m/min by pressing the
SPEED left knob (6 - Fig.5) until LED 3 - Fig.5 lights up and turn the same
knob.
Adjust the inductance by pressing the left knob (6 - Fig.5) until LED 53
- Fig. 2 - Fig. 5 lights up and turn the same knob - less inductance
(narrower arc, more penetration) and more inductance (wider arc,
more filling).
Adjust the UP SLOPE time (wire speed ramp) by pressing the right
knob 9 (Fig.5) until LED 5 (Fig.6) lights up and turn the same knob.
Regulate the POST GAS time (gas flow after welding, which protects
the weld bead from oxidation and cools the torch), by pressing the
right knob (9 - Fig.5) until LED 3 - Fig.6 lights up and turn the same
knob.
Adjust BURN BACK (the width of the wire at the exit of the gun, at the
end of the welding), by pressing the right button 9 (Fig.5) until LED 2
(Fig.6) lights up and turn the same button.
HOLD After welding, the device automatically shows the average voltage and
current values of the last weld for 2 seconds on the respective
displays. By pressing the left knob (6 - Fig. 5) until LED 4 - Fig. 5 lights
up, you can check at any time the average values of welding voltage
and welding current of the last weld with the HOLD function.
